This permit incorporates and shall be considered a Construction Permit for any engine replacement performed in accordance with this AOS, and the permittee shall be allowed to perform such engine replacement without applying for a revision to this permit or obtaining a new Construction Permit. A.1 Engine Replacement • The following AOS is incorporated into this permit in order to deal with a compressor engine breakdown or periodic routine maintenance and repair of an existing onsite engine that requires the use of either a temporary or permanent replacement engine. "Temporary" is defined as in the same service for 90 operating days or less in any 12 month period. "Permanent" is defined as in the same service for more than 90 operating days in any 12 month period. The 90 days is the total number of days that the engine is in operation. If the engine operates only part of a day, that day shall count as a single day towards the 90 -day total. The compliance demonstrations and any periodic monitoring required by this AOS are in addition to any compliance demonstrations or periodic monitoring required by this permit. All replacement engines are subject to all federally applicable and state -only requirements set forth in this permit (including monitoring and record keeping). The results of all tests and the associated calculations required by this AOS shall be submitted to the Division within 30 calendar days of the test or within 60 days of the test if such testing is required to demonstrate compliance with NSPS or MACT requirements. Results of all tests shall be kept on site for five (5) years and made available to the Division upon request. The permittee shall maintain a log on -site and contemporaneously record the start and stop date of any engine replacement, the manufacturer, date of manufacture, model number, horsepower, and serial number of the engine(s) that are replaced during the term of this permit, and the manufacturer, model number, horsepower, and serial number of the replacement engine. In addition to the log, the permittee shall maintain a copy of all Applicability Reports required under section A.1.2 and make them available to the Division upon request. A.1.1 The permittee may temporarily replace an existing compressor engine that is subject to the emission limits set forth in this permit with an engine that is of the same manufacturer, model, and horsepower or a different manufacturer, model, or horsepower as the existing engine without modifying this permit, so long as the emissions from the temporary replacement engine comply with the emission limitations for the existing permitted engine as determined in section A.2. Measurement of emissions from the temporary replacement engine shall be made as set forth in section A.2. A.1.2 The permittee may permanently replace the existing compressor engine with an engine that is of the same manufacturer, model and horsepower without modifying this permit so long as the emissions from the permanent replacement engine comply with 1) the permitted annual emission limitations for the existing engine, 2) any permitted short-term emission limitations for the existing permitted engine, and 3) AIRS ID: 123/9A95 Page 23 of 27 Public Health and Environment Air Pollution Control Division the applicable emission limitations as set forth in the Applicability Report submitted to the Division with the Air Pollutant Emissions Notice (APEN) for the replacement engine (see http://www.cdphe.state.co.us/ap/oilgaspermittinq.html for example applicability report formats). Measurement of emissions from the permanent replacement engine and compliance with the applicable emission limitations shall be made as set forth in section A.2. An Air Pollutant Emissions Notice (APEN) that includes the specific manufacturer, model and serial number and horsepower of the permanent replacement engine shall be filed with the Division for the permanent replacement engine within 14 calendar days of commencing operation of the replacement engine. The APEN shall be accompanied by the appropriate APEN filing fee, a cover letter explaining that the permittee is exercising an alternative operating scenario and is installing a permanent replacement engine, and a copy of the relevant Applicability Reports for the replacement engine. Example Applicability Reports can be found at http://www.cdphe.state.co.us/ap/oilgaspermitting.html. This submittal shall be accompanied by a certification from a person legally authorized to act on behalf of the source indicating that "based on the information and belief formed after reasonable inquiry, the statements and information included in the submittal are true, accurate and complete". This AOS cannot be used for permanent engine replacement of a grandfathered or permit exempt engine or an engine that is not subject to emission limits. The permittee shall agree to pay fees based on the normal permit processing rate for review of information submitted to the Division in regard to any permanent engine replacement. A.2 Portable Analyzer Testing Note: In some cases there may be conflicting and/or duplicative testing requirements due to overlapping Applicable Requirements. In those instances, please contact the Division Field Services Unit to discuss streamlining the testing requirements. Note that the testing required by this Condition may be used to satisfy the periodic testing requirements specified by the permit for the relevant time period (i.e. if the permit requires quarterly portable analyzer testing, this test conducted under the AOS will serve as the quarterly test and an additional portable analyzer test is not required for another three months). The permittee may conduct a reference method test, in lieu of the portable analyzer test required by this Condition, if approved in advance by the Division. The permittee shall measure nitrogen oxide (NOX) and carbon monoxide (CO) emissions in the exhaust from the replacement engine using a portable flue gas analyzer within seven (7) calendar days of commencing operation of the replacement engine. All portable analyzer testing required by this permit shall be conductedusing the Division's Portable Analyzer Monitoring Protocol (ver March 2006 or newer) as found on the Division's website at: http://www.cdphe.state.co.us/ap/down/portanalyzeproto.pdf Results of the portable analyzer tests shall be used to monitor the compliance status of this unit. For comparison with an annual (tons/year) or short term (lbs/unit of time) emission limit, the results of the tests shall be converted to a lb/hr basis and multiplied by the allowable operating hours in the month or year (whichever applies) in order to monitor compliance. If a source is not limited in its hours of operation the test results will be multiplied by the maximum number of hours in the month or year (8760), whichever applies. For comparison with a short-term limit that is either input based (lb/mmBtu), output based (g/hp-hr) or concentration based (ppmvd @ 15% O2) that the existing unit is currently subject to or the replacement AIRS ID: 123/9A95 Page 24 of 27 Are or Public Health and Environment Air Pollution Control Division S engine will be subject to, the results of the test shall be converted to the appropriate units as described in the above -mentioned Portable Analyzer Monitoring Protocol document. If the portable analyzer results indicate compliance with both the NOX and CO emission limitations, in the absence of credible evidence to the contrary, the source may certify that the engine is in compliance with both the NOX and CO emission limitations for the relevant time period. Subject to the provisions of C.R.S. 25-7-123.1 and in the absence of credible evidence to the contrary, if the portable analyzer results fail to demonstrate compliance with either the NOX or CO emission limitations, the engine will be considered to be out of compliance from the date of the portable analyzer test until a portable analyzer test indicates compliance with both the NOX and CO emission limitations or until the engine is taken offline. A.3 Applicable Regulations for Permanent Engine Replacements A.3.1 Reasonably Available Control Technology (RACT): Reg 3, Part B § II.D.2 All permanent replacement engines that are located in an area that is classified as attainment/maintenance or nonattainment must apply Reasonably Available Control Technology (RACT) for the pollutants for which the area is attainment/maintenance or nonattainment. Note that both VOC and NOX are precursors for ozone. RACT shall be applied for any level of emissions of the pollutant for which the area is in attainment/maintenance or nonattainment, except as follows: In the Denver Metropolitan PM10 attainment/maintenance area, RACT applies to PM10 at any level of emissions and to NOX and SO2, as precursors to PM10, if the potential to emit of NOX or SO2 exceeds 40 tons/yr. For purposes of this AOS, the following shall be considered RACT for natural-gas fired reciprocating internal combustion engines: VOC: The emission limitations in NSPS JJJJ CO: The emission limitations in NSPS JJJJ NOX: The emission limitations in NSPS JJJJ SO2: Use of natural gas as fuel PM10: Use of natural gas as fuel As defined in 40 CFR Part 60 Subparts GG (§ 60.331) and 40 CFR Part 72 (§ 72.2), natural gas contains 20.0 grains or less of total sulfur per 100 standard cubic feet. A.3.2 Control Requirements and Emission Standards: Regulation No. 7, Sections XVI. and XVII.E (State -Only conditions). Control Requirements: Section XVI Any permanent replacement engine located within the boundaries of an ozone nonattainment area is subject to the applicable control requirements specified in Regulation No. 7, section XVI, as specified below: Rich burn engines with a manufacturer's design rate greater than 500 hp shall use a non- selective catalyst and air fuel controller to reduce emission. Lean burn engines with a manufacturer's design rate greater than 500 hp shall use an oxidation catalyst to reduce emissions. AIRS ID: 123/9A95 Page 25 of 27 of Public Health and Environment Air Pollution Control Division The above emission control equipment shall be appropriately sized for the engine and shall be operated and maintained according to manufacturer specifications. The source shall submit copies of the relevant Applicability Reports required under Condition A.1.2. Emission Standards: Section XVILE — State -only requirements Any permanent engine that is either constructed or relocated to the state of Colorado from another state, after the date listed in the table below shall operate and maintain each engine according to the manufacturer's written instructions or procedures to the extent practicable and consistent with technological limitations and good engineering and maintenance practices over the entire life of the engine so that it achieves the emission standards required in the table below: Max Engine HP Construction or Relocation Date Emission Standards in G/hp-hr NOx CO VOC 100<Hp<500 January 1, 2008 January 1, 2011 2.0 1.0 4.0 2.0 1.0 0.7 500<Hp July 1, 2007 July 1, 2010 2.0 1.0 4.0 2.0 1.0 0.7 The source shall submit copies of the relevant Applicability Reports required under Condition A.1.2 A.3.3 NSPS for spark ignition internal combustion engines: 40 CFR 60, Subpart JJJJ A permanent replacement engine that is manufactured on or after 7/1/09 for emergency engines greater than 25 hp, 7/1/2008 for engines less than 500 hp, 7/1/2007 for engines greater than or equal to 500 hp except for lean burn engines greater than or equal to 500 hp and less than 1,350 hp, and 1/1/2008 for lean burn engines greater than or equal to 500 hp and less than 1,350 hp are subject 40 CFR 60, Subpart JJJJ. An analysis of applicable monitoring, recordkeeping, and reporting requirements for the permanent engine replacement shall be included in the Applicability Reports required under Condition A.1.2. Any testing required by the NSPS is in addition to that required by this AOS. Note that the initial test required by NSPS Subpart JJJJ can serve as the testing required by this AOS under Condition A.2, if approved in advance by the Division, provided that such test is conducted within the time frame specified in Condition A.2. Note that under the provisions of Regulation No. 6. Part B, section I.B. that Relocation of a source from outside of the State of Colorado into the State of Colorado is considered to be a new source, subject to the requirements of Regulation No. 6 (i.e., the date that the source is first relocated to Colorado becomes equivalent to the manufacture date for purposes of determining the applicability of NSPS JJJJ requirements). However, as of November 1, 2008 the Division has not yet adopted NSPS JJJJ. Until such time as it does, any engine subject to NSPS will be subject only under Federal law. Once the Division adopts NSPS JJJJ, there will be an additional step added to the determination of the NSPS. Under the provisions of Regulation No. 6, Part B, § LB (which is referenced in Part A), any engine relocated from outside of the State of Colorado into the State of Colorado is considered to be a new source, subject to the requirements of NSPS JJJJ. A.3.4 Reciprocating internal combustion engine (RICE) MACT: 40 CFR Part 63, Subpart ZZZZ A.3.4.1 Area Source for HAPs AIRS ID: 123/9A95 Page 26 of 27 Public Health and Environment Air Pollution Control Division A permanent replacement engine located at an area source that commenced construction or reconstruction after June 12, 2006 as defined in § 63.2, will meet the requirements of 40 CFR Part 63, Subpart ZZZZ by meeting the requirements of 40 CFR Part 60, Subpart JJJJ. An analysis of the applicable monitoring, recordkeeping, and reporting requirements for the permanent engine replacement shall be included in the Applicability Reports required under Condition A.1.2. Any testing required by the MACT is in addition to that required by this AOS. Note that the initial test required by the MACT can serve as the testing required by this AOS under Condition A.2, if approved in advance by the Division, provided that such test is conducted within the time frame specified in Condition A2. A.3.4.2 Major source for HAPs A permanent replacement engine that is located at major source is subject to the requirements in 40 CFR Part 63 Subpart ZZZZ as follows: Existing, new or reconstructed spark ignition 4 stroke rich burn engines with a site rating of more than 500 hp are subject to the requirements in 40 CFR Part 63 Subpart ZZZZ. New or reconstructed (construction or reconstruction commenced after 12/19/02) 2 stroke and 4 stroke lean burn engines with a site rating of more than 500 hp are subject to the requirements in 40 CFR Part 63 Subpart ZZZZ. New or reconstructed (construction or reconstruction commenced after 6/12/06) 4 stroke lean burn engines with a site rating of greater than or equal to 250 but less or equal to 500 hp and were manufactured on or after 1/1/08 are subject to the requirements in 40 CFR Part 63 Subpart ZZZZ. New or reconstructed (construction or reconstruction commenced after 6/12/06) 2 stroke lean burn or 4 stroke rich burn engines with a site rating of 500 hp or less will meet the requirements of 40 CFR 63, Subpart ZZZZ by meeting the requirements of 40 CFR 60, Subpart JJJJ. New or reconstructed (construction or reconstruction commenced after 6/12/06) 4 stroke lean burn engines with a site rating of less than 250 hp will meet the requirements of 40 CFR 63, Subpart ZZZZ by meeting the requirements of 40 CFR 60, Subpart JJJJ. An analysis of the applicable monitoring, recordkeeping, and reporting requirements for the permanent engine replacement shall be included in the Applicability Reports required under Condition A.1.2. Any testing required by the MACT is in addition to that required by this AOS. Note that the initial test required by the MACT can serve as the testing required by this AOS under Condition A.2, if approved in advance by the Division, provided that such test is conducted within the time frame specified in Condition A.2. A.3.5 Additional Sources The replacement of an existing engine with a new engine is viewed by the Division as the installation of a new emissions unit, not "routine replacement" of an existing unit. The AOS is therefore essentially an advanced construction permit review. The AOS cannot be used for additional new emission points for any site; an engine that is being installed as an entirely new emission point and not as part of an AOS- approved replacement of an existing onsite engine has to go through the appropriate Construction/Operating permitting process prior to installation.

AIRS Point Section 12 — Regulatory Review Regulation 1 - Particulate, Smoke, Carbon Monoxide and Sulfur Dioxide Section II.A.1 - Except as provided in paragraphs 2 through 6 below, no owner or operator of a source shall allow or cause the emission into the atmosphere of any air pollutant which is in excess of 20% opacity. This standard is based on 24 consecutive opacity readings taken at 15 -second intervals for six minutes. The approved reference test method for visible emissions measurement is EPA Method 9 (40 CFR, Part 60, Appendix A (July, 1992)) in all subsections of Section II. A and B of this regulation. litgulation 2 — Odor Section I.A - No person, wherever located, shall cause or allow the emission of odorous air contaminants from any single source such as to result in detectable odors which are measured in excess of the following limits: For areas used predominantly for residential or commercial purposes it is a violation if odors are detected after the odorous air has been diluted with seven (7) or more volumes of odor free air. Page 6 Regulation..3 - APENs,,Construction=Permits, Operating Permits, PSD Part A-APEN Requirements Applicant is required to file an APEN since emissions exceed applicable thresholds. Part B — Construction Permit Exemptions Applicant is required to obtain a permit since emissions exceed applicable thresholds.

Listed in "Notes to permit holder." 006 None 007 NSPS 0000: Standards of Performance for Crude Oil and Natural Gas Production, Transmission and Distribution. For fugitive emissions at natural gas processing plants subject to NSPS 0000. This subpart establishes emission standards and compliance schedules for the control of volatile organic compounds (VOC) and sulfur dioxide (S02 ) emissions from affected facilities that commence construction, modification or reconstruction after August 23, 2011. Is this source at a "natural gas processing plant?" No; it is being called a compressor station Is this source subject to NSPS 0000? Yes WHY? Operator believes that the compressors are subject to NSPS 0000. Since we have devised a condition for the compressors in fugitives, the fugitives will be subject to NSPS 0000 and not directly the compressor engines. Regulation 7— Volatile Organic Compounds 001-005 Section XVLB Applicant is located in NAA and thus required to install NSCR on rich burn engine rated greater than 500 hp. Section XVII.E. Engines are subject to emission standards unless NSPS JJJJ and MACT ZZZZ requirements ultimately are applicable. 006 Is this source subject to the control requirements of MACT HH? (Regulation 8 -Hazardous Air Pollutants review). No Is this source subject to the exemptions under MACT HH (i.e. throughput exemption less than 3 MMSCFD or benzene exemption of less than 1984 Ib/yr)? No This source is subject to review for the Regulation 7 control requirements. 006 Section XII.H: Is this source located in the non -attainment area? Yes This source is subject to Regulation 7, Section XII.H. Uncontrolled actual emissions of volatile organic compounds from the still vent and vent from any gas -condensate -glycol (GCG) separator (flash separator or flash tank), if present, shall be reduced by at least 90 percent through the use of air pollution control equipment. 006 Section XVII.D (State only enforceable). Applicant is required to reduce VOC emissions from this dehydrator by at least 90% since uncontrolled VOC emissions are greater than the 15.0 TPY threshold. 007 Section XII.G.1. Applicant is located in NAA but since it is not a gas processing facility, the requirements are not applicable. Regulation 8 - Hazardous Air Pollutants 001-005 MACT ZZZZ: Area source requirements are not currently adopted in Colorado regulations. Listed in "Notes to permit holder." Page 7 MACT HH: If facility is MAJOR source for HAP (summation of HAPS of dehydrators and fugitives greater than 25 TPY total or 10 TPY single HAP), then all glycol dehydrators at this facility are subject to MACT HH. If facility is an area source of HAP, only TEG dehydrators are subject to MACT HH. 1.Is facility a production field facility per 63.761 (Refer to Section 14 for definition)? Yes 2.If facility is defined as a production facility, then is it a major source of HAPS when summing up dehydrator and flash tank emissions? No 006 3.1s this facility considered MAJOR for HAPS? No 4.Is this source subject to MACT HH? No 5.WHY? This facility is an area source of HAP and MACT HH area source requirements apply to this TEG dehydrator. This dehydrator is not located within an urban cluster or within two miles of an urban area, and is subject to the optimal circulation rate work practice standard in HH. 007 MACT HH: This facility is an area source of HAPs.

The engines have not yet been ordered so exact dates are not yet known for establishing regulatory applicability. The engines will most likely be subject to area source requirements under MACT ZZZZ and NSPS JJJJ requirements. The application consisted of 5 engine APENS, but DCP will only be running 4 engines at a time (one APEN reflected 0 emissions on the APEN). I talked with Brian Taylor regarding the 0 emissions and how I did not feel comfortable having no emissions for the 5th engine, for when the 5th engine turns on (C-5), there will be no permit limits in the permit. He agreed, and then discussed a combined emission limit for all 5 engines as in permit 12WE2039. I agreed that I have done that before on other permits, and can do that with this one. So, the 5 engines will have one emission limit for NOx, CO and VOC. Page 9 AIRS Point 006 TEG Dehydrator This emissions point covers emissions from one triethylene glycol (TEG) dehydrator that treats field gas prior to sending the gas on for additional processing at a gas plant. The TEG dehydrator will have a maximum capacity of 50 MMscfd based on the APEN. The pump specifications are not yet known but the requested glycol recirculation rate is 24.0 gallons per minute. The still vent will be routed to a condenser and then to an enclosed combustor. The flash tank emissions are routed back to the plant inlet via a vapor recovery unit (VRU). The reboiler is rated at 2:86 MMbtu/hr. In order to determine emissions, the operator used GRI GlyCALC 4.0. The source assumed an inlet gas temperature of 100°F and pressure of 900 psig and I confirmed these values were used in the GIyCALC report. The permitted glycol recirculation rate of 24.0 gallons per minute is also used in the GlyCALC report. Since the facility is a proposed, new facility, a site -specific gas analysis was not available for emission calculations. The source stated that they compiled various gas samples from the area which they felt to be representative of the gas for the facility. This method is appropriate for a new facility. An extended gas analysis will be required as part of the self -certification process to confirm emissions. Gly-Calc-Uncontrolled Emission factors VOC = ((382.3927+262.9553)*2000)/(50*365) = 70.72 lb/mmscf (matches APEN) Benzene = ((76.2803+2.7629)*2000)/(50*365) = 8.66 lb/mmscf (matches APEN) Toluene = ((96.7547+2,3678)*2000)/(50*365) = 10.86 lb/mmscf (matches APEN) Ethylbenzene = ((4.2218+0.0626)*2000)/(50*365) = 0.47 lb/mmscf (matches APEN) Xylenes = ((47.9212+0.5126)*2000)/(50*365) = 5.31 lb/mmscf (matches APEN) N -hexane = ((21.0763+18.3240)*2000)/(50*365) = 4.32 lb/mmscf (matches APEN) MACT HH includes requirements for both major and area sources of HAPs. The definition of major source for MACT HH (63.761) states: (3) For facilities that are production field facilities, only HAP emissions from glycol dehydration units and storage vessels with the potential for flash emissions shall be aggregated for a major source determination. For facilities that are not production field facilities, HAP emissions from all HAP emission units shall be aggregated for a major source determination. The following definitions from 63.761 are also needed to determine major source applicability: Production field facilities means those facilities located prior to the point of custody transfer Custody transfer means the transfer of hydrocarbon liquids or natural gas: after processing and/or treatment in the producing operations, or from storage vessels or automatic transfer facilities or other such equipment, including product loading racks, to pipelines or any other forms of transportation. For the purposes of this subpart, the point at which such liquids or natural gas enters a natural gas processing plant is a point of custody transfer. Natural gas processing plant (gas plant) means any processing site engaged in the extraction of natural gas liquids from field gas, or the fractionation of mixed NGL to natural gas products, or a combination of both. Based on the definitions above, this source qualifies as a production field facility since it is prior to entering a natural gas processing plant. For a production field facility, only HAP emissions from dehys and storage tanks with flash emissions are included for determining major source status. The facility's storage tanks are pressurized bullet tanks and there is only one dehy. Using the requested throughput limit of 50 MMscfd and glycol recirculation rate of 24 gpm, uncontrolled VOC emissions from the dehy are 645.35 tpy VOC, uncontrolled total HAP emissions are 270.3 tpy, and uncontrolled toluene emissions are 99.1 tpy. Controlled total HAP emissions from the dehy are 11.3 tpy and controlled toluene emissions are 4.4 tpy. Controlled emissions are based on 100% of flash tank emissions being recycled and 95% control of still vent emissions. The facility is an area source for MACT HH. As specified in 63.760(b)(2), the only affected sources for area sources are TEG dehydrators. Page 10 The source cannot meet the processing exemption limit in 63.764(e)(i) because the proposed process limit is 50 MMscfd which exceeds the exemption limit of 3.002 MMscfd. The source cannot meet the . benzene exemption limit of 1,984 lb/yr in 63.764(e)(ii) because controlled benzene emissions are estimated at 8180 lb/yr. Based on the location information provided in the application, the source is not within an UA Plus Offset or within a UC boundary. Thus, as an area source outside of a UC boundary, it is eligible for the optimal circulation rate work practice standard in 63.764(d)(2). These requirements will be listed in the permit. Regulation 7, Section XVII.D requires emission control standards for dehydrators with uncontrolled emissions of VOC greater than 15 tons per year from all the dehydrators on site. As discussed above, uncontrolled VOC emissions are 645.4 tpy. Section XVII.B.4 states that dehydrators subject to an emission control requirement in a federal MACT standard are not subject to requirements under Section XVII. This dehy is subject to a work practice standard under MACT HH, not an emission control requirement; thus, the dehy is still subject to the requirements of Section XVII.D. Further, since the source will be located in a non -attainment area, the dehy is also subject to the requirements of Regulation 7, Section XII.H. While the requirements of Section XII and XVII appear duplicative, both Regulation 7 requirements will be listed in the permit since they are both applicable. The unit is equipped a reboiler rated at 2.86 MMbtu/hr. Since the reboiler burner has a design rate less than 5 mmbtu/hr, then it is APEN-exempt (Regulation No. 3, Part A, II.D.1.k), and is therefore also exempt from construction permitting requirements (Regulation no. 3, Part B, II.D.1.a). Criteria pollutant emission levels for this unit are based on factors from AP -42, Chapter 1.4, Small Boilers < 100 MMBtu/hr (7/1998). AIRS Point 007 Fugitive Emissions from Equipment Leaks A permit will be issued because the uncontrolled VOC emissions are greater than 5 TPY (permit threshold). Source is subject to RACT requirements. Operator provided some RACT discussion, but I followed a similar permit issued to DCP and used that RACT condition. AIRS Point 008 Enclosed combustor A permit will be issued because the uncontrolled CO emissions are greater than 2 TPY and the total facility uncontrolled CO emissions are greater than 5 TPY (permit threshold). Insignificant Activities The source provided emission estimates for several insignificant activities at the facility. Since APENs were not submitted for these insignificant activities, emissions and regulatory applicability were not evaluated for these activities/points. Emissions listed in the application were included in the history file to understand total facility emissions but otherwise not reviewed as part of this permit action, The facility's insignificant activities include one 2.86 MMBtu/hr dehy reboiler, two 30,000 gallon pressurized condensate storage tanks, pressurized condensate loadout, compressor blowdowns, two 100 bbl produced water tanks, one 1000 gallon methanol tank, 200 gallon lube oil tank, 1000 gallon glycol tanks and 80 bbl drain tank. Facility Wide Comments DCP is proposing to construct and operate a natural gas compression facility with a capacity of 50 MMscfd. This stationary source will be located in Weld County which is currently considered a non -attainment area for ozone. The facility will install emissions controls in order to be considered a synthetic minor source for Non -attainment New Source Review (NANSR) requirements that would have otherwise been triggered due to emissions of nitrogen oxides (NOx) and volatile organic compounds (VOC) in excess of 100 tons per year. The facility will also be considered synthetic minor source for Prevention of Significant Deterioration (PSD) requirements that would have otherwise been triggered due to emissions of carbon monoxide (CO) in excess of 250 tons per year. The source will be a synthetic minor source of criteria pollutants and HAP emissions for Title V Operating Permit program. DCP is a "midstream" natural gas company and thus does not own, operate, or control any oil or natural gas leases, production wells or production lease sites (E&P sites). Additionally, DCP stated on 3/13/13 that no DCP compressor stations are currently located, or will be located, within a quarter mile of the SLW compressor station. DCP also stated that no DCP compressor stations or gas plants that are greater than a quarter mile from the SLW compressor station will be wholly dependent with SLW. In the application's cover letter, DCP noted that the design of this compressor station is very similar to the Libsack Compressor Station (Permit11WE1475)and might be able to use that permit to help streamline the permitting process. I used permits 11WE1475 and 12WE2039 for guidance.
